Description

VARIABLE GUIDE APPARATUS AND VEHICLE INCLUDING THE SAME

The present invention relates to a deformable guide member and an automobile including the same.

In general, when the vehicle travels along the road at high speed, the lift force is applied to the vehicle by the air flow flowing along the body of the vehicle, so that the rear part of the vehicle is lifted. In order to reduce the air resistance of such a vehicle, various types of air spoilers are installed depending on the vehicle type.

Such an air spoiler for a vehicle is generally fixedly installed at the rear of the vehicle, and a downward force is generated in the lower direction of the air spoiler by a difference in air flow velocity of the fluid flowing along the outer surface of the air spoiler when the vehicle is driven. This can improve the driving stability of the vehicle.

And, a vehicle that is optimized for aerodynamics and airflow can show better performance in terms of improved handling, stability and fuel consumption, so the use of an air spoiler is a very important device for racing vehicles.

However, the conventional air spoiler for a vehicle has to generate an appropriate down force at a low speed and a high speed depending on the speed of the vehicle, but has a structure fixed to the vehicle body in a straight shape, and thus does not generate a sufficient down force. In addition, since the conventional air spoiler for a vehicle is fixed at a certain angle, it is difficult to cope with the airflow that changes according to the speed of the vehicle, so there is a problem in that the driving stability of the vehicle is deteriorated.

It was devised based on the technical background as described above, and an object of the present invention is to provide a variable guide member capable of efficiently adjusting the air resistance of a vehicle by easily deforming the shape of the variable guide member.

The variable guide member according to an embodiment of the present invention is connected to a vehicle body and is formed by lamination of a plurality of composite material layers, and is disposed between the wing part and the composite material layer of the wing part, which are variable to control the flow of air, , may include a wire that is deformed according to the application of power.

The wire may include a tube that surrounds the outer surface of the wire and is fixed inside the body.

The composite material layer may be a prepreg made of carbon fiber and epoxy.

The wing portion may have a through hole extending in the vertical direction therein, and the wire may be disposed in the through hole.

It is fixed to the vehicle body to increase the traction force between the vehicle body and the ground, and the end further includes a body part to which the wing part is connected, and the wing part has one end fixed by the body part and the other end part by deformation of the wire. may be variable.

In the wing portion, a first fluid supply path may be formed on an upper side of the through hole, and a second fluid supply path may be formed on a lower side of the through hole.

An incompressible fluid supplied from any one of the first fluid supply path and the second fluid supply path may flow into the through hole, and the position of the wire may vary according to the incompressible fluid inflow.

The wing portion may be connected to a lower side of the through hole to form a fluid passage extending to the body portion.

The body portion may have a space formed therein, and the fluid passage may be connected to an upper side of the space portion and an inflow passage communicating with the outside may be connected to a lower portion of the space portion.

The body portion may have an inlet hole connected to the inflow path formed on an upper surface thereof, so that air flowing through the upper side of the body portion may be introduced into the inflow path through the inlet hole.

The body part may include a piston installed in the space part to partition the space part up and down, and the space part may be filled with an incompressible fluid on an upper side of the piston and air may be filled on a lower side of the piston.

The piston moves in the vertical direction of the space according to the pressure of the air flowing into the space, so that the incompressible fluid flows into and out of the through hole, and the incompressible fluid flows into and out of the through hole. The position may be variable.

The body portion may include a guide portion installed on the upper portion to guide the air flowing on the upper side of the body portion toward the inlet hole.

A vehicle according to another embodiment of the present invention may include the above-described deformable guide member.

The variable guide member according to an embodiment of the present invention has a shape variable through a shape memory alloy wire, so that it is possible to efficiently control the air resistance of the vehicle.

Hereinafter, with reference to the accompanying drawings, the embodiments of the present invention will be described in detail so that those of ordinary skill in the art to which the present invention pertains can easily implement them. The present invention may be embodied in many different forms and is not limited to the embodiments described herein.

In order to clearly explain the present invention, parts irrelevant to the description are omitted, and the same reference numerals are given to the same or similar elements throughout the specification.

In addition, since the size and thickness of each component shown in the drawings are arbitrarily indicated for convenience of description, the present invention is not necessarily limited to the illustrated bar.

Referring to FIG. 1 , the deformable guide member 100 may be installed transversely to the upper rear end of the vehicle 10 . For example, the deformable guide member 100 may be disposed on an installation platform formed to have a predetermined height above the rear end of the vehicle 10 .

1 to 5 , the deformable guide member 100 may include a wing portion 120 and a wire 131 .

The wing part 120 is in the form of a bar extending in the left and right direction of the vehicle 10 , and is connected to the vehicle 10 , and may serve to increase the traction force between the vehicle 10 and the ground. The wing part 120 may be disposed in the transverse direction of the vehicle 10 and fixed on an installation platform formed at the upper rear end of the vehicle 10 . In addition, the inclination angle of the wing unit 120 may vary according to the speed of the vehicle 10 to vary the down force.

The wing part 120 may be made of a composite material layer. The composite material layer is a pre-impregnated material (prepreg) in which the reinforcing fibers are impregnated with a thermoplastic or thermosetting resin, and may have a sheet shape having the same predetermined thickness.

For example, the resin of the composite material layer may be an epoxy resin. Epoxy resin can be stably bonded to fibers due to its high adhesive strength, and has excellent resistance to moisture and chemical substances and thus has excellent durability. In addition, since the epoxy resin has high flexibility and strength, the shape change of the deformable guide member 100 may smoothly occur while maintaining strength above a certain level. As another example, the reinforcing fibers of the composite material layer may be carbon fibers. At this time, the carbon fibers impregnated in the resin may be arranged in one direction.

The wire 131 may be a shape memory alloy (SMA) wire. The shape memory alloy is a material that deforms when power is applied, and the degree of deformation varies depending on the strength of the applied power, and when the power is cut off, it can return to the shape before power is applied.

The wire 131 is embedded in the wing portion 120 , and may be arranged in a longitudinal direction and a vertical direction of the wing portion 120 . A plurality of these wires 131 are connected in series, and a wire module 130 including the plurality of wires 131 may be formed.

2 to 4 , the aforementioned wire module 130 may be formed in plurality. The plurality of wire modules 130 may be respectively disposed on the upper and lower portions of the wing portion 120 , and the plurality of wire modules 130 are the length of the wing portion 120 in the upper and lower portions of the wing portion 120 . It may be disposed to be spaced apart along the direction. For example, as shown in FIG. 4 , eight wire modules 130a, 130b, 130c, 130d, 130e, 130f, 130g, 130h may be arranged in two rows and four columns in the wing unit 120 .

The tube 140 may be formed to surround the outer surface of the wire 131 . For example, the tube 140 may be a Kapton tube formed of polyimide. The tube 140 may have high adhesion to the composite material layer of the wing unit 120 . Accordingly, by mounting the tube 140 on the wire 131 and embedding it in the wing part 120 , separation of the wire 131 and the composite material layer of the wing part 120 can be prevented.

The fixing unit 150 may include a first fixing member 151 , a second fixing member 152 , a first coupling member 153 , and a second coupling member 154 .

The first fixing member 151 and the second fixing member 152 may be arranged in a bar shape in the longitudinal direction of the wing unit 120 . The first fixing member 151 and the second fixing member 152 may be respectively disposed on the upper and lower portions of the plurality of wires 131 to fix the ends of the plurality of wires 131 .

The first fastening member 153 and the second fastening member 154 may be fastened to each other, thereby fixing the first fixing member 151 and the second fixing member 152 to each other. For example, the first fastening member 153 may be a bolt and the second fastening member 154 may be a corresponding nut. The first fastening member 153 penetrates the first and second fastening members 152 in the vertical direction and is coupled to the second fastening member 154, so that the first and second fastening members 152 are in close contact with each other to form a plurality of the plurality of fastening members. One end of the wire 131 may be fixed.

Also, the first fixing member 151 may have a protruding member 151a protruding from its lower surface in the longitudinal direction. The second fixing member 152 may have an insertion groove 152a formed on its upper surface in the longitudinal direction. In this case, the insertion groove 152a may be formed to correspond to the protruding member 151a.

At this time, after positioning the end of the wire 131 between the first fixing member 151 and the second fixing member 152 , when the first fixing member 151 and the second fixing member 152 are pressed together The wire 131 may be pressed by the protruding member 151a to be inserted into the insertion groove 152a.

In addition, since the end of the wire 131 is pressed by the outer surface of the protruding member 151a and the insertion groove 152a, it may be bent to correspond to the shape of the outer surface of the protruding member 151a and the insertion groove 152a. Accordingly, a phenomenon in which the wire 131 and the fixing part 150 are separated can be prevented.

On the other hand, one end of the plurality of wires 131 is fixed by the fixing unit 150 , and the other ends of the plurality of wires 131 are stretched to a predetermined length by the linear guide device and then fixed by the fixing unit 150 . . Accordingly, the wire 131 is fixed to the fixing unit 150 while being pre-strained, and when power is applied to the wire 131 in the pre-strained state, it can be stably driven.

2 and 3 , a control unit 20 and a power supply unit 30 may be installed in the vehicle 10 . The control unit 20 may control the power supply unit 30 of the power supply unit 30 to adjust whether power supplied to the variable guide member 100 is supplied. The power supply unit 30 may be connected to a plurality of wire modules inside the wing unit 120 , respectively. The power supply unit 30 may apply a current to the wire 131 constituting the wire module 130 .

That is, when the power supply unit 30 is operated using the control unit 20 , a current is applied to the wire 131 and the length of the wire 131 may be deformed in proportion to the strength of the supplied power. Accordingly, as shown in FIG. 5 , the angle of inclination of the deformable guide member 100 may be varied while the wing portion 120 is bent.

Meanwhile, the controller 20 may individually control the plurality of wire modules 130 . For example, the control unit 20 may operate the power supply unit 30 according to a signal input from the operation unit (not shown) of the vehicle 10 to selectively supply power to the plurality of wire modules 130 .

For example, when power is applied to the wire module 130 located on the upper portion of the wing unit 120, the length of the wire 131 is deformed, and the upper end of the wing unit 120 is compressed and deformed, and the inclination angle can be varied. have. In addition, when power is applied to the wire module 130 located at the lower portion of the wing unit 120 , the length of the wire 131 is deformed and the lower end of the wing unit 120 is compressed and deformed so that the inclination angle can be varied. As another example, by applying power to the wire module 130 located on the left or right side of the wing unit 120 , only the inclination angle of the left end or the right end of the wing unit 120 may be varied.

That is, the wing unit 120 may be divided into a plurality of zones by the plurality of wire modules 130 , and the wing unit 120 selectively supplies power to the plurality of wire modules 130 by the control unit 20 . ) By varying only a selected region of several regions, the wing portion 120 can be varied to have various angles and shapes.

Most of the configuration of the second embodiment of the present invention is similar to the configuration of the deformable guide member 100 of the embodiment of the present invention, and a detailed description thereof will be omitted, and the configuration and differences of the embodiment of the present invention are different. Only the configuration in which there is will be described.

Referring to FIG. 6 , the deformable guide member 100 may further include a body part 110 connected to the wing part 120 .

The body 110 may be connected to the vehicle 10 to serve to increase the traction between the vehicle 10 and the ground. The body part 110 may be disposed in the transverse direction of the vehicle 10 and be fixed on an installation platform formed at the upper rear end of the vehicle 10 .

A wing portion 120 extending rearward may be connected to an end of the body portion 110 . For example, the body portion 110 may be formed with protrusions 110a extending rearward from the upper end and lower end, respectively. In this case, an adhesive layer 111 may be formed on the rear surface and the protrusion 110a of the body portion 110 . The wing part 120 may be inserted between these protrusions 110a and coupled thereto. At the upper end and lower end of the protrusion 110a, the coupling member 112 may be disposed to penetrate up to the wing portion 120 . That is, the bonding force between the body part 110 and the wing part 120 may be increased by the adhesive layer 111 and the coupling member 112 .

The wing part 120 is connected to the rear end of the body part 110 , and may vary a down force by varying an inclination angle according to the speed of the vehicle 10 . For example, the wing portion 120 may have an insertion portion 120b protruding to be inserted into the space between the projection portions 110a of the body portion 110 . The insertion part 120b is formed to correspond to the space between the protrusions 110a, so that the wing part 120 may be inserted into the body part 110 and fixed by the adhesive layer 111 and the coupling member 112.

Also, referring to FIG. 9 , the wing part 120 may be formed by stacking a plurality of composite material layers 121 and 122 . The composite material layers 121 and 122 are prepregs in which the reinforcing fibers are impregnated with a thermoplastic or thermosetting resin, and may have a sheet shape having the same predetermined thickness. For example, the resin of the composite material layers 121 and 122 may be an epoxy resin, and the reinforcing fiber may be a carbon fiber. At this time, the carbon fibers impregnated in the resin may be arranged in one direction.

The composite material layer may include a first composite material layer 121 and a second composite material layer 122 . The first composite material layer 121 is formed so that the arrangement direction of the carbon fibers coincides with the longitudinal direction of the wing unit 120 , and the second composite material layer 122 has the arrangement direction of the carbon fibers of the wing unit 120 . It may be formed to be perpendicular to the longitudinal direction.

In this case, the wing part 120 may be formed by cross-stacking a plurality of first composite material layers 121 and second composite material layers 122 . For example, as shown in FIG. 9, two layers of the second composite material layer 122, four layers of the first composite material layer 121, and two layers of the second composite material layer 122 are sequentially stacked. can be

Referring to FIG. 9 , the wire 131 may be disposed between the plurality of composite material layers. For example, the wire 131 may be disposed between the plurality of first composite material layers 121 at the upper end of the wing unit 120 . That is, the wire 131 is deflected upward from the center layer of the wing unit 120 and is buried, and the first composite material layer 121 may be formed on the upper end and lower end of the wire 131 .

Meanwhile, referring to FIGS. 7 and 8 , a control unit 20 and a power supply unit 30 may be installed in the vehicle 10 . That is, when the power supply unit 30 is operated using the control unit 20, a current is applied to the wire 131 and the length of the wire 131 is deformed in proportion to the strength of the supplied power, and accordingly, the wing unit ( As the 120 is bent, the inclination angle of the deformable guide member 100 may be varied. For example, when the length of the wire 131 is deformed, the composite material layer located on the upper end of the wire 131 is compressed and deformed, and the inclination angle of the deformable guide member 100 may be changed.

10 is a side view of a deformable guide member according to a third embodiment of the present invention. 11 is a cross-sectional view of the wing shown in FIG.

10 and 11 , the variable guide member 100 according to the third embodiment of the present invention includes a body portion 110 , a wing portion 120 , a wire 131 and a tube 140 . and a through hole 120a, a first fluid supply path 161 and a second fluid supply path 162 may be formed in the wing part 120 . In addition, a fluid storage unit 50 and a fluid supply unit 60 may be further installed in the vehicle 10 to supply a fluid into the through hole 120a. Most of the configuration of the third embodiment of the present invention is similar to that of the deformable guide member 100 of the second embodiment of the present invention, and a detailed description thereof will be omitted, and the configuration and differences of one embodiment of the present invention Only this configuration will be described.

The through hole 120a is a hole extending in the vertical direction inside the wing part 120 , and the wire 131 on which the tube 140 is mounted may be disposed in the through hole 120a. For example, the through hole 120a may be formed by passing through a plurality of composite material layers. A first fluid supply path 161 and a second fluid supply path 162 may be formed at upper and lower sides of the through hole 120a, respectively.

Meanwhile, the vehicle 10 may further include a fluid storage unit 50 and a fluid supply unit 60 . The fluid storage unit 50 may accommodate an incompressible fluid therein. An incompressible fluid is a fluid whose density hardly changes even with changes in pressure or temperature. The fluid supply unit 60 may be a pump, and may pump the fluid of the fluid storage unit 50 and supply it to the first fluid supply path 161 or the second fluid supply path 162 .

Referring to FIG. 11 , when the fluid F is supplied to the first fluid supply path 161 , the fluid may be introduced into the lower side of the through hole 120a. At this time, as the fluid flows, it is possible to press the lower side of the wire 131 disposed in the through hole 120a. Accordingly, when the filling of the fluid F into the through hole 120a through the first fluid supply path 161 is completed, the wire 131 may be located at the upper end of the through hole 120a.

In addition, when the fluid F is supplied to the second fluid supply path 162 , the fluid may be introduced into the upper side of the through hole 120a. At this time, as the fluid flows, the upper side of the wire 131 disposed in the through hole 120a may be pressed. Accordingly, when the filling of the fluid F in the through hole 120a through the second fluid supply path 162 is completed, the wire 131 may be located at the lower end of the through hole 120a. That is, the position can be changed by supplying a fluid to any one of the first fluid supply path 161 and the second fluid supply path 162 to move the wire 131 in the vertical direction.

When the wire 131 is located at the upper end of the through hole 120a, it may be deflected upward from the center surface of the wing unit 120 . At this time, when power is applied to the wire 131, the length of the wire 131 is deformed, and the first composite material layer 121 disposed on the upper end of the wire 131 is compressively deformed to bend the wing portion 120. have. Accordingly, the inclination angle of the deformable guide member 100 may be varied upward.

When the wire 131 is positioned at the lower end of the through hole 120a, it may be deflected downward from the center surface of the wing part 120 . At this time, when power is applied to the wire 131, the length of the wire 131 is deformed, and the first composite material layer 121 disposed at the lower end of the wire 131 is compressively deformed to bend the wing portion 120. have. Accordingly, the inclination angle of the deformable guide member 100 may be varied downward.

12 is a perspective view of a deformable guide member according to a fourth embodiment of the present invention. 13 is a side view of the deformable guide member shown in FIG. 12 ;

12 and 13 , the deformable guide member 100 according to the fourth embodiment of the present invention may further include a guide unit 170 . In addition, the body portion 110 has an inlet hole 171 , an inflow passage 172 , a space portion 173 , and a piston 174 are formed, and the wing portion 120 has a through hole 120a and a fluid passageway ( 175) may be formed. Most of the configuration of the fourth embodiment of the present invention is similar to that of the deformable guide member 100 of the embodiment of the present invention, a detailed description thereof will be omitted, and the configuration and differences of the embodiment of the present invention Only the configuration in which there is will be described.

The guide part 170 may be installed on the upper part of the body part 110 and formed along the longitudinal direction of the body part 110 . For example, the guide portion 170 may have a lower end fixed to the body portion 110 and curved forward toward the upper end. As the guide portion 170 is formed to be curved, a space may be formed between the guide portion 170 and the body portion 110 . Accordingly, the air flowing along the upper portion of the vehicle 10 when the vehicle 10 is driven may flow into the space between the guide portion 170 and the body portion 110 .

On the other hand, the body portion 110 may be formed with an inlet hole 171 , an inflow path 172 , a space portion 173 , and a piston 174 .

The inlet hole 171 is formed on the upper surface of the body part 110 , and may be formed so as to have a position corresponding to the space between the guide part 170 and the body part 110 . The inflow hole 171 may be connected to the inflow path 172 formed inside the body 110 .

The inflow path 172 may be formed to extend in the vertical direction inside the body 110 , and one end may be connected to the inflow hole 171 . Accordingly, the air flowing into the lower portion of the guide unit 170 may be introduced into the inflow path 172 through the inlet hole 171 .

The space 173 may be formed inside the body 110 to have a predetermined volume. For example, the space portion 173 may be formed to extend in the longitudinal direction of the body portion (110). The space portion 173 may have a fluid passage 175 connected to the upper side and an inlet passage 172 connected to the lower side.

A piston 174 may be horizontally disposed in the space 173 . At this time, the space portion 173 may be filled with a fluid F in the upper portion with respect to the piston 174 , and air may be introduced in the lower portion through the inflow path 172 .

On the other hand, the piston 174 is disposed in the horizontal direction in the space portion 173, it can move in the vertical direction of the space portion (173). For example, when the traveling speed of the vehicle 10 is increased, the intensity of the air introduced into the inlet hole 171 may be increased, and the pressure of the air introduced to the lower side of the space portion 173 may increase.

At this time, when the pressure of the air flowing into the space 173 is higher than the pressure of the fluid filled in the upper part of the space 173 , the piston 174 may move upward. Accordingly, since the piston 174 moves upward by air pressure and pressurizes the fluid F, the fluid F may move to the through hole 120a through the fluid passage 175 .

In addition, when the traveling speed of the vehicle 10 is reduced, as the intensity of the air introduced into the inlet hole 171 is weakened, the pressure of the air introduced to the lower side of the space portion 173 may be reduced. At this time, the piston 174 may move downward by its own weight. Accordingly, the piston 17 may move downward, and the fluid F may be introduced into the upper portion of the space 173 through the fluid passage 175 .

The fluid passage 175 may be formed in the wing portion 120 to connect the space portion 173 and the through hole 120a. The fluid passage 175 may serve as a passage through which the fluid F flows.

The through hole 120a is a hole extending in the vertical direction inside the wing part 120 , and the wire 131 on which the tube 140 is mounted may be disposed in the through hole 120a. In addition, a fluid passage 175 may be connected to a lower side of the through hole 120a. Accordingly, the through-hole 120a may allow the fluid F to be introduced or discharged through the fluid passage.

For example, when the driving speed of the vehicle 10 increases and the air pressure at the lower side of the space portion 173 becomes higher than the pressure of the fluid F, the piston 174 moves upward and pressurizes the fluid F, Accordingly, the fluid F may be introduced into the through hole 120a through the fluid passage 175 . At this time, as the fluid F flows into the lower side of the through hole 120a, the wire 131 may move upward.

At this time, when power is applied to the wire 131 in a state in which the wire 131 is deflected upward from the center surface of the wing unit 120 , the length of the wire 131 is deformed and the upper end of the wing unit 120 is compressed and deformed. and can be bent. Accordingly, the inclination angle of the deformable guide member 100 may be varied upward. At this time, as the wire 131 is spaced apart from the center surface of the wing part 120, the inclination angle of the wing part 120 may increase.

In addition, when the traveling speed of the vehicle 10 decreases and the air pressure at the lower side of the space 173 becomes lower than the pressure of the fluid F, the piston 174 moves downward, and thus the fluid F passes through it. It may flow into the space 173 from the hole 120a. At this time, as the fluid F filled in the through hole 120a is discharged, the wire 131 may move downward.

At this time, when power is applied to the wire 131 in a state in which the wire 131 is deflected downward from the center surface of the wing unit 120 , the length of the wire 131 is deformed and the lower end of the wing unit 120 is compressed and deformed. can be bent Accordingly, the inclination angle of the deformable guide member 100 may be varied downward. At this time, as the wire 131 is spaced apart from the center surface of the wing part 120, the angle of inclination of the wing part 120 may increase.

That is, the position of the wire 131 disposed in the through hole 120a may be varied by using a change in air pressure according to the traveling speed of the vehicle 10 , and accordingly, the variable guide member 100 by the wire 131 may be changed. ) of the inclination angle and inclination direction can be adjusted.
